To all whom/it may concern.-

Be it knowri that L-ROBERT H. MCDOWELL, a resident ofSalem, in thecounty of Columbiana and State of Ohio, have invented certain newanduseful Improvements in Fountain Brushes; and I do hereby declare thefollowingto be a full, clear, and exact description of the invention,such as Will enable others skilled in the art to which it ap pertains tomake and use the same.

My invention relates to improvements in fountain-brushes, the object ofthe invention being to provide an improved construction of brush orsponge especially designed for foundry use and provide an improvedreservoir for filling the same.

There is great need in foundries of a brush or sponge for supplyingwater under perfect control of the molder which will enable him tohandle the brush or sponge without wetting his hands, as this is asource of great annoyance, resulting in sorc hands, and a furtheressential is to provide means for supplying the device with water whichdoes not consume the time of the molder.

My improvements fulfil all the above re quirements and consist incertain novel features of construction and combinations and arrangementsof parts, as will be more fully hereinafter described, and pointed outin the claim. p

In the accompanying drawings, Figure I is 2. view in vertical sectionill Htrating my inipr vemcnts, and Figs. 2 and 3 are-views oi details ofconstruction.

1 represents my improved fountain brush or s 'iongc, and 2 a reservoirto support and fill the same. Thcbrush comprises'a tube 3, having anelastic bulb 4 socurml to one end either b y being sprung into a recessin the tube, as shown in l ig. 1, or clamped to the tube by a nut 5, asshown in Fig. 2, or may be secured in any other approved manner. Thedischarge end of tube 3 is slightly contracted to receive the brush 6.The brush preferably comprises a number of line hairs, around the middlc of which a wire 7 is twisted to hold the brush together, and thiswire is inserted in the tube and drawn thercthrough to bend or fold thehairs into the form of a brush, as shown, the inner end of the wire 7being-secured to a cro sswire 8 at the inner end of tube 3 to hold thebrush in the tube. The

brush loosely fits the discharge end of the tube to enable a great orlesser flow of Water or other liquid employed, as the operator maydesire, and the wire 7 insures the brush always remaining in operativeposition. The reservoir 2, which may be of any material, is made with acentral neck 9 at its .top, preferably rolled back to form a smooth seatfor the bulb 4 to support the brush in the reservoir. An air-vent 10 isprovided in the neck portion 9 of the reservoir to admit air freely tothe reservoir to permit the bulb to freely draw the Water from thereservoir up into the tube and bulb as the latter expands.

The operation of my improvements is as follows: The reservoir 2 isfilled with the liquid to be used, and the bulb 4 is comervoir with thebrush end of the tube 3 subnwrgedv in the water. As the bulb expands itwill draw the liquid therein to fill the same, the vent 10 in thereservoir permitting the bulb to freely take the water from thereservoir. When the molder desires the brush he grasps the bulb, and ashe moves the brush over the mold hc compresses the bulb to eject thequantity of liquid desired, and when through with the brush he insertsit into the reservoir and permits the brush to fill itself ready for thenext operation.

A great many slight changes might be made in the general form andarrangement of the parts described, but consider myself at liberty tomake such slight changes and alterations as fairly fall within thespirit and scope of my invention.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent is having a filling and discharging bulb at oneend, of a reservoir having an opening to receive the brush and supportthe bulb, said reservoir having a vent to admit air and permit thecontents of the reservoir to be drawn into the device by means of thebulb while said bulb is resting onthe reservoir.

, In testimony whereof I have signed this ing' Witnesses.
